Worked on the karlseguin/quickjs repository to enhance build reliability and cross-compiler compatibility, specifically targeting GCC 14.2. Addressed a format-related issue in quickjs.c by casting pointer variables to void pointers within module_trace calls, which resolved build failures and enabled successful compilation with modern toolchains. Focused on debugging and code maintenance using C programming and build systems expertise, ensuring smoother onboarding for developers working with updated compilers. The work involved careful handling of C pointers and attention to compiler-specific requirements, resulting in improved build stability and reduced friction for contributors integrating QuickJS with newer development environments.
